Procedure for the realization of a container and container obtained by this procedure

ABSTRACT

A procedure and a container realized in accordance with this procedure are described.  
     In accordance with the present invention the cross section through the container form on the lower side consists of two different ellipse-halves with the main circle of the smaller ellipse ( 2 ) and the secondary circle of the larger ellipse ( 3 ) being identical and the intersection edge at the smaller ellipse ( 2 ) being along the main axis ( 4 ) at the large ellipse along the secondary axis ( 4 ) and both the ellipse-halves being put together at their intersection edges and in the cross section on the upper side the larger and smaller ellipses (in  2 ′ and  3 ′) having exchanged positions, otherwise the upper and lower sides being identical and if at the bottom the smaller ellipse-half is at the left of the intersection edge and the larger half ellipse to the right thereof, then in the cross section this is reversed through the upper side and all the cross sections having intersection edges extending mutually parallel.

The present invention relates to a procedure for the realization of a container and a container obtained by this procedure in accordance with the classifying part of claims 1 and 5.

Containers of known type are realized by molding, drawing, or employing a tool for material removal et cetera. In all these containers, either there must be a particular shape or the forming takes place by means of tools or even by hand. In the case of these containers they are first of all cans, bottles, or even goblets, glasses et cetera.

In the production of containers of this type there is thus the difficulty of working, in the case of mass production, with economical molds, i.e. molds that can be realized rapidly in accordance with a specific program. This also applies to the control of tools, if they are used, which must be controlled for example by a CCN machine.

The general purpose of the present invention is to make available a procedure in the case where a container might be formed in accordance with a particular program and the container might be obtained in a repeatable manner with great precision in accordance with this procedure.

This purpose is achieved by a procedure for the realization of containers in accordance with the characterizing parts of claim 1 and a container in accordance with the characterizing part of claim 5.

If there is adopted as external contour for the lower edge of a container a cross section presenting an ellipse-half of one size and an ellipse-half of another size or a semicircle with the larger ellipse-half having a secondary circle identical to the main circle of the smaller ellipse and both these halves mutually connected, then at the connection point along the vertical axis of the container with constant advancement along the height on one side of the connection point a piece of the smaller ellipse-half being removable and replaceable by a piece of the larger ellipse-half and on the other side of the connection point a piece of the larger ellipse-half being removable and replaceable by a piece of the smaller ellipse-half in such a manner that at the upper edge the smaller ellipse positions are exchanged with those of the larger ellipse.

If the second cross-section half is a semicircle, it this can be identical either with the main circle or with the secondary circle of the ellipse-half.

In one embodiment the cross section of the container contour can be simply rotated around the common center of the main circle and the secondary circle continuously along the vertical axis to reach at least and in particular the upper edge in which the positions of the cross-section halves are exchanged.

Further details and characteristics are set forth in the claims and the description given below of preferred embodiments with reference to the figures of the annexed drawing in which:

FIG. 1 shows a cross section of a container contour at the lower edge of the container on the left side of the drawing and at the upper edge of the container on the right side of the drawing in a first embodiment of the present invention; and

FIG. 2 shows a cross section in a second embodiment of the present invention.

In FIG. 1 reference number 1 shows the external contour of the container as a whole. The cross section through the container form at the lower side consists of two different ellipse halves. The main circle of the small ellipse 2 and the secondary circle of the larger ellipse 3 are identical. The intersection edge of the small ellipse 2 is along the main axis 4 and of the large ellipse along the secondary axis 4 which both coincide. Both the ellipse-halves are assembled at their intersection edge. The cross section at the upper side, the large ellipse and the small ellipse have exchanged position at 2′ and 3′ but otherwise the upper and lower sides are identical. If at the bottom, half of the small ellipse is to the left of the intersection edge and the large ellipse-half of to the right thereof, then this is reversed in the cross section through the upper side. All the cross sections have intersection edges extending mutually parallel.

Both from the lower side towards the upper side and vice versa, one does as follows: in the case of the small ellipse-half, beginning from the intersection edge, a piece is removed and replaced by a piece of the large ellipse-half. The large ellipse-half piece begins on the main vertex and is added to the remaining piece of the small ellipse beginning from the main vertex. The tangents of the ellipse piece removed and of the one added form the same angle with their respective symmetry axes. Both the ellipse pieces are put together in such a manner that they have a common tangent at the point of junction.

In the case of the large ellipse-half, beginning at the intersection edge (hence on the secondary vertex) a piece is removed and replaced in the center (hence on the symmetry axis 5) of the respective piece of the small ellipse in such a manner that its secondary vertex is on the symmetry axis. The rest as above.

That which is removed from the small ellipse as measured on the main axis, on one of the sides, must be added on the other side of the intersection edge. This means that both the pieces of the main axis of the small ellipse together always involve the total length of their main axis. Proportionately to the length of the main axis of the small ellipse on both sides of the intersection edge, the intersection edge migrates in the longitudinal section from one side upward.

In that respect, there is the following alternative. In the case of half of the large ellipse, beginning at the intersection edge, a piece is removed and replaced by a piece of the small ellipse-half. The piece of the small ellipse-half begins at the secondary vertex and is added to the remaining piece of the large ellipse beginning at the secondary vertex. Both pieces of the ellipse are assembled in such a manner that they have a common tangent at the point of junction.

In the case on the small ellipse-half, beginning at the intersection edge (hence at the main vertex), a piece is removed and replaced in the center (hence at the symmetry axis 5) from the respective piece of the large ellipse with the rest as above.

That which was removed from the large ellipse as measured on the secondary axis at one of the sides must be added on the other side of the intersection edge. This means that both pieces of the main axis of the large ellipse together always involve the length of their main axis. Proportionately to the length of the secondary axis of the large ellipse on both sides of the intersection edge, the intersection edge migrates in longitudinal section or along the height from one side to the other.

In the resulting embodiment of FIG. 2, there is shown an external contour 6 in which both of the lower ellipses 7 and 8 and both of the upper ellipses are not the same or instead of the second pair of ellipses a circle 9 and 10 is used. Thus the added piece of the large ellipse no longer begins at the main vertex but a bit beyond in the direction of the secondary vertex (or respectively the added piece of the small ellipse is no longer at the secondary vertex but a bit beyond in the direction of the main vertex) and specifically the smaller the piece of added circle or piece of added ellipse and proportionately to the difference in the eccentricity of both the ellipses or of the semicircle.
